FIELD

The present application relates to the field of communication technologies, and in particular, to a method and apparatus for transferring machine learning model parameters.

BACKGROUND

As one of key methods of artificial intelligence, the machine learning was proposed in the 1950s. With the development of machine learning technologies, the Neural Network (NN) or Artificial Neural Network (ANN) has been proposed, which is a general-purpose model to facilitate the construction of models in machine learning inspired by biological neural network. A simple neural network includes an input layer, an output layer and a hidden layer (if needed), and each layer includes neurons.

In order to solve complex nonlinear problems, the number of hidden layers in the designed neural network is gradually increased to form a Deep Neural Network (DNN), and the corresponding learning method is deep machine learning or deep learning. Various types of deep neural network models have been developed, including DNN, Recurrent Neural Network (RNN), Convolutional Neural Network (CNN), etc. Since the 2010s, the deep learning, as an important branch of machine learning, has gained widespread attention and explosive growth.

The introduction of machine learning into wireless mobile communication system can solve complex problems of the mobile communication system or improve performance. However, due to the complex composition of the wireless mobile communication system and the numerous manufacturers, how to deploy/update the machine learning model trained on the network side to the terminal side has become a systematic problem, which requires a unified solution.

Therefore, the embodiments of the present application provide a method and apparatus for transferring machine learning model parameters, to transfer the machine learning model trained on the network side to the terminal side.

Here, the method and device are based on the same application concept. Since the principle of solving the problem in the method is similar to that in the device, the implementations of the device and method can refer to each other, and the repeated description thereof will be omitted.

The embodiments of the present application may be applicable to various systems, especially a 5G system or a 6G system. For example, the applicable systems may be: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS) system, Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide interoperability for Microwave Access (WiMAX) system, 5G system and 5G NR system, etc. These systems all include terminal devices and network devices.

The wireless terminal device can communicate with one or more core networks via the RAN, and the wireless terminal device can be a mobile terminal, such as a mobile telephone (or called “cellular” telephone), and a computer with the mobile terminal, for example, can be a portable, pocket, handheld, computer built-in or vehicle-carried mobile device, and they exchange the voice and/or data with the radio access network.

The embodiments of the present application will be described below in detail with reference to the drawings of the specification. It should be noted that the showing order of the embodiments of the present application only represents the sequential order of the embodiments, but does not represent the pros and cons of the embodiments.

The embodiments of the present application propose a solution for deploying/updating a machine learning model trained on the system side to the terminal side in wireless mobile communication system by using native services.

The native service described in the embodiments of the present application may, for example, refer to a type of service constructed between the base station and the terminal in the mobile communication system in order to solve the complex problems of the mobile communication system or improve the performance, and is not a function service directly required by the user. The service object thereof is a network itself or an operator, so it is called native service. The machine learning model (its corresponding function) to be deployed can be regarded as a native service, and the deployment or update of the machine learning model can be performed in the manner of service deployment or update. Simply put, the machine learning model can be regarded as an application (APP), and the deployment/update of the model is the download and installation process of the APP. The more complex model can be deployed in the manner of a native service, and it is also more conducive to the knowledge protection of the model itself.

A way to construct a start point and an end point of a native service on RAN side (including a base station and a terminal) respectively, as shown in FIG. 1 and FIG. 2 , includes a user plane and a control plane respectively.

In one embodiment, the control plane mainly executes processes such as service registration process and radio resource application of native services on the RAN side. Here, the service registration process initiated by the terminal side is taken as an example to illustrate, that is, a specific native service (such as “channel estimation of terminal side” service executed on the terminal side) needs to register with the operating system on the processor where it is located before execution, and needs to obtain the authorization from the base station during registration, to prevent the terminal from arbitrarily executing unauthorized native services. The registration process is generally initiated by an application layer of a main body executing the service (for example, the main body executing the service of the “channel estimation of terminal side” is the terminal), and is processed through a wireless network layer (referring to 5G wireless network layer, which may include RRC, PDCP, RLC, MAC and PHY layers) under the application layer, to form an air interface signal to be sent to the base station; after the base station receives the air interface signal, the signal is processed through a wireless network layer (referring to 5G wireless network layer, which may include PHY, MAC, RLC, PDCP and RRC layers) to obtain the service registration application initiated by the terminal. After checking the application, the base station will confirm the registered information, and then send it to the terminal after being processed through the wireless network layers under the application layer; and the terminal obtains the authorization information from the base station side after receiving the air interface signal and processing the air interface signal through the wireless network layers.

The user plane mainly deals with the user data in native services on the RAN side. The data may be generated by the application layer (such as the test data used by the terminal to perform a measurement service), or may be generated in the wireless network layer under the control of the control plane (such as a reference signal used in the “channel estimation of terminal side” service, which is generated by the PHY layer in the wireless network layer). Here, the test data used by the terminal to perform the measurement service is taken as an example to illustrate. The data is generated by the application layer on the base station side and is processed through the wireless network layer (referring to the 5G wireless network layer, which may include SDAP, PDCP, RLC, MAC and PHY layers), to form an air interface signal to be sent to the terminal; after receiving the air interface signal, the terminal side invokes the measurement service to process the air interface signal.

The main flow of updating a machine learning model is as shown in FIG. 3 . Based on the above constructed native services of the RAN system, a specific method for deploying/updating a machine learning model is as follows.

Step 1: when the base station decides to deploy/update the machine learning model for a target functional component on the terminal side, an AI-native service master management component in the base station selects a corresponding machine learning model file from a machine learning model library.

Here, the target functional component is, for example, channel estimation, signal detection, channel decoding, Channel Quality Indicator (CQI) measurement, synchronization detection, transmit antenna selection, etc. The AI-native service master management component is located in the application layer on the base station side, and is mainly configured to provide native services with the service registration function and the function of applying for transmission resources between the terminal and the base station. The machine learning model file is generally understood as an executable program file, such as .exe. Generally, multiple files are included and packaged into a compressed file package, such as .zip.

Step 2: the AI-native service master management component in the base station applies for the transmission resource between the terminal and the base station from a transmission resource management component on the base station side.

Step 3: the AI-native service master management component in the base station uses the transmission resource obtained by application to send the machine learning model file from the machine learning model library to an AI-native service slave management component on the terminal side, along with the corresponding information of the target functional component.

The AI-native service slave management component is located in the application layer on the terminal side.

The information of the target functional component includes, for example, the name of the target functional component, as shown in the second column of Table 1.

Step 4: the AI-native service slave management component on the terminal side distributes the machine learning model file to the target functional component on the terminal side according to the received information of the target functional component.

Step 5: the target functional component on the terminal side, after receiving the machine learning model file distributed by the AI-native service slave management component, performs installation and notifies the AI-native service slave management component.

Step 6: the AI-native service slave management component on the terminal side applies for the transmission resource between the terminal and the base station from the transmission resource management component on the base station side.

Step 7: the AI-native service slave management component on the terminal side applies for service registration to the AI-native service master management component in the base station by using the transmission resource obtained by application.

Step 8: the AI-native service slave management component on the terminal side launches a service included in the machine learning model newly deployed/updated in the target functional component after obtaining a service registration permission from the AI-native service master management component on the base station side.

For example, a list of the machine learning model library is shown in Table 1 below, and a compression package of a machine learning model file corresponding uniquely to a machine learning model number can be found according to the machine learning model number.
